    Report of the Second Advisory Roundtable on the Assessment of Inland Fisheries, Rome, 25–27 November 2019 2021

    The Second Advisory Roundtable on the Assessment of Inland Fisheries was convened in partnership with United States Geological Service (USGS), from 25 to 27 November 2019. It reviewed the progress of work that had been initiated as a response to the recommendations of the “Advisory Roundtable on the Assessment of Inland Fisheries” that was convened in partnership with the United States Geological Service (USGS) and Michigan State University (MSU) in FAO Rome, from 8 to 10 May 2018. The Second Roundtable covered two aspects of the assessment of inland fisheries. As its first task, the Roundtable reviewed a threat mapping framework developed by USGS and the University of Florida, which seeks to provide a robust assessment method for inland fisheries and the associated ecosystems/basins upon which they depend. This is intended to support the management of aquatic systems and the continued delivery of ecosystem services. The status map that the analysis provides is a visual (and quantifiable) relative indication of the levels of anthropogenic and natural environmental pressures to inland fisheries at the basin or sub-basin level. Five major threats to inland fisheries (and their 21 sub-threat categories) were scored according to global studies and modeling.

    New approaches for the improvement of inland capture fishery statistics in the Mekong Basin 2002

      Inland capture fisheries provide a valuable contribution to food security in the Mekong Basin. However, official tiol estimates of this contribution have consistently been lower than estimates derived from more focused and localized fishery surveys. Thus, inland capture fisheries are undervalued by decision makers and development agencies. The poor state of knowledge on inland fisheries arises from the diverse ture of inland fisheries, that fisheries are often small-scale and dispersed over la rge areas, that inland fishers have idequate political power, the misconception that inland fisheries are not valuable, the local consumption or bartering of inland fisheries harvest, and the excessive power of certain stakeholders that do not want the actual value known. Development activities may then ippropriately focus on other sectors at the expense of rural communities that depend on inland fisheries. Accurate information on the contribution of inland fisheries is essential for responsible development. Key uses of accurate information identified at the Expert Consultation were: i) to determine the status and trends of the fishery and the environment, ii) to assess correctly the value of inland fisheries, iii) to allocate appropriate resources to the inland fishery sector, and iv) to fulfill intertiol obligations. In general, information collection in the Mekong is based on figures collected from government fishery officers assessing catch and effort data. These methods are best s uited to formal, large-scale fisheries, but are ippropriate for many of the small- scale, informal fisheries of the Mekong Basin. Altertive approaches are being developed and evaluated that include individual fishers, household and communities, and proxy measures of fishery yield. Besides the traditiol catch and effort surveys, approaches to improve information on inland fisheries were identified to include agriculture surveys, consumption studies (including household surveys), market surveys, g eo-referenced information, habitat classification and measurement, and establishment of co-magement or fishery user groups. In the lower Mekong Basin, the primary information need was yield. The informal and formal fishery sectors must be treated differently to obtain accurate information on both. The results from focused studies on particular habits or fisheries can be extrapolated to provide information on a wider area within the basin. There is a strong seasol component to the fisheries that must be considered and the capacity and status of local fishery officers must be increased in order to facilitate accurate reporting. Useful information already exists in project reports, with NGOs and IGOs, and in government offices that should be alyzed, and stakeholders in inland fisheries should form partnerships with other users of inland water resources.

    An audit of inland capture fishery statistics - Africa 2012
    Also available in:

    Catches from African inland capture fisheries are rising at about 3.7 percent per year. The combined reported catches in 2007 were 2 463 975 tonnes. Catch reports from the 20 highest producing countries (representing more than 94 percent of the total catch) are analysed for consistency by a subjective evaluation based on the form of the data set, knowledge of trends in climate, predicted yield patterns from models of similar fisheries and the results of independent research. The other African countries are examined in less detail. The audit shows that 37 percent of countries reported catches as still rising, 28 percent as falling and 35 percent as stable. The reported catch from about 72 percent of countries is judged to need some clarification before these trends can be fully understood. Particular clarification is needed for the Sahelian zone countries as catches are reported as rising there despite negative climatic conditions. Clarification is also needed for the Congo basin where a historic lack of data collection makes it impossible to estimate the true production and any trends in catch. The regional trend is probably misrepresenting the historical catch levels and hence caution should be used when referencing to the increasing catch figure. In addition, the relatively stable catch per person depicted by this trend should also be referenced with care and could even have been decreasing in the last decades. In conclusion, the potential and fu ture development of inland capture fisheries of Africa cannot be fully assessed until clarification is given on the above mentioned areas relating to the reported statistics. Hence, there is a need for further information to interpret the trends in inland fisheries in Africa and to resolve the paradox of apparently threatened resources and ever growing catches.
